Just like the mod has ±1 and ±5 per request item in the requester chests,
it woulld be convenient to have ֶ͏ֶ*2 and /2 per item, or better, for all requests in the requester chest. 2 buttons for all requests
That can (mostly) be done without a mod. Click the "rename" button on the logistic group, and you'll have a "multiplier" box where you can set a multiple of the request.
